The invention provides a crystal immersing and cutting method which is applied in a multi-wire cutting device for cutting a crystal silicon ingot. The multi-wire cutting device at least comprises a cutting table for carrying a crystal silicon ingot to be cut and a multi-wire cutting system for running cutting wires, and the method comprises the following steps: firstly setting a liquid containing groove on the cutting table of the multi-wire cutting device; secondly, placing the crystal silicon ingot to be cut in the liquid containing groove; then injecting a cutting liquid into the liquid containing groove, and immersing the crystal silicon ingot to be cut in the cutting liquid; and further running the cutting wires at a high speed so that the cutting wires oppress the liquid containing groove and are immersed in the crystal silicon ingot to be cut in the cutting liquid so as to further enable the cutting wires to cut the crystal silicon ingot to be cut in the cutting liquid while cutting the side wall of the liquid containing groove and further enable the cutting liquid to flow out from a gap on the cut side wall of the liquid containing groove during the cutting process so as to be conductive to circulation. By adopting the method, the problem that cutting sand which is brought into a cutting region during the cutting process is rare, and the cutting efficiency is further greatly improved.
Description
technical field [0001] The invention relates to a multi-wire cutting technology, in particular to a crystal immersion cutting method applied in a multi-wire cutting device to increase the amount of sand in the cutting fluid to improve production efficiency. Background technique [0002] Multi-wire cutting technology is a relatively advanced crystalline silicon processing technology in the world at present. Its principle is to use a high-speed moving steel wire to drive the cutting blade attached to the steel wire to rub against hard and brittle materials such as semiconductors to achieve the cutting effect. Compared with the traditional saw blade, grinding wheel and inner circle cutting, the multi-wire cutting technology has the advantages of high efficiency, high productivity and high precision. The multi-wire cutting technology is currently the most widely used cutting technology for hard and brittle materials such as semiconductors. [0003] Existing multi-wire cutting eq...
